A swivel-linker for use in a necklace assembly for holding a pair of eyeglasses includes a necklace-side connector and a holder-loop side connector. The necklace-side connector is attachable to a necklace. The holder-loop side connector has a connector opening configured to receive an eyeglass-holder loop having an eyeglass opening passing therethrough shaped and dimensioned to receive a temple piece of a pair of eyeglasses. The connector opening is configured to allow the holder-loop-side connector to rotate about the eyeglass-holder loop when the eyeglass-holder loop is received in the connector opening. The holder-loop-side connector includes a pin protruding away from the connector opening. The necklace-side connector has a cavity configured to receive the pin and to rotatably connect the necklace-side connector and the holder-loop-side connector to allow a full rotation between the necklace-side connector and the holder-loop-side connector by a swivel axis. Rotation of the holder-loop-side connector relative to the necklace-side-connector and/or the holder-loop-side connector relative to the eyeglass-holder-loop relieves twisting induced in the necklace in response to the holder-loop-side connector receiving the eyeglass-holder loop, the necklace-side connector being connected to the necklace and the necklace being worn about the neck of a wearer with a pair of eyeglasses in a folded-closed configuration removably pendulously held in the eyeglass-holder loop with a temple piece extending downwardly from one side of the eyeglass-holder loop opening and a lens frame of the eyeglasses extending downwardly from an opposite side of the eyeglass opening.

FIELD OF THE INVENTION

The present invention relates to a holder for a pair of eyeglasses and,more particularly, to a necklace assembly for holding eyeglasses whichcan be worn about the neck.

BACKGROUND ART

Generally, persons who wear eyeglasses remove and replace themfrequently during the course of a day. When an eyeglass wearer removeshis or her eyeglasses, it is usually desired to keep the eyeglassesclose at hand in order to be able to replace them conveniently. Uponremoving eyeglasses, therefore, eyeglass wearers frequently place theeyeglasses in a pocket of a shirt or coat, or hang the eyeglasses from aneck opening of a sweater or a blouse by inserting a temple piece of theeyeglasses down inside the garment. However, eyeglasses may fall from ashirt or coat pocket or from a neck opening of a sweater or blouse whenthe eyeglass wearer bends over, which is at best an annoyance and whichcan result in damage to the eyeglasses. In addition, certain styles ofgarments do not have pockets or neck openings suitable for holdingeyeglasses.

Thus, a need exists for an eyeglass holder necklace assembly which holdsa pair of eyeglasses neatly and securely even as a wearer of thenecklace assembly moves about.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In accordance with the principles of the present invention, a necklaceassembly for holding a pair of eyeglasses is provided. In an exemplaryembodiment depicted in FIG. 1, a necklace assembly 10 for holding a pairof eyeglasses 12 includes an elongated necklace 14 and an eyeglassholder assembly 20.

Necklace 14 is depicted in FIG. 1 as a simple cord, and such cord may beflexible and/or resilient for example. Alternatively, necklace 14 may bean ornamental jewelry chain, such as the jewelry chain necklaces 15 and17 shown in FIGS. 7-8 or a string of beads. For example, the jewelrychain necklace 15 could be a jewelry chain made of gold, silver or otherprecious metal or of a mock-tortoise-shell or mock-ivory plasticmaterial. Also, necklace 14 could be a flexible and/or resilient cordhaving beads (not shown) strung along it.

At opposite ends of necklace 14 are a first necklace end 16 and a secondnecklace end 18. Eyeglass-holder assembly 20 is connected to firstnecklace end 16 and second necklace end 18. Eyeglass-holder assembly 20includes an eyeglass-holder ring 22, a first swivel linker 24, and asecond swivel linker 26.

First swivel linker 24 and second swivel linker 26 are constructedidentically. As shown best in FIGS. 2-4, second swivel linker 26includes a necklace-side connector 28 and a holder-ring-side connectorring 30 (also referred to herein as a holder-loop-side connector).Necklace-side connector 28 and holder-ring-side connector ring 30 ofswivel linker 26 are rotatably connected together by a pin-and-socketarrangement.

In particular, a top end 27 of necklace-side connector 28 of secondswivel linker 26 is fixedly connected to second necklace end 18 and abottom end 29 of necklace-side connector 28 is rotatably connected toholder-ring-side connector ring 30. More specifically, necklace-sideconnector 28 may be cylindrically shaped. Also, necklace-side connector28 includes a cavity 21 which may receive second necklace end 18. Aninterior surface 23 defining cavity 21 may be glued to second necklaceend 18 to fixedly connect necklace-side connector 28 to second necklaceend 18. Interior surface 23 may also include a groove 31 for receiving alinker pin 32 of holder-ring-side connector ring 30. Interior surface 23may be cylindrically shaped, exclusive of groove 31.

Linker pin 32 projects radially outwardly from an outer circumferentialsurface 130 of a loop portion 132 of connector ring 30. Linker pin 32 issubstantially rotationally symmetric about an axis 140 which defines aswivel axis associated with second swivel linker 26 as depicted in FIG.2. Swivel axis 140 may be substantially aligned with a longitudinal axisof second end 18 of necklace 14 and/or a longitudinal axis ofnecklace-side connector 28. Linker pin 32 has a head portion 34 spacedapart from outer circumferential surface 130 of holder-ring-sideconnector ring 30 and a neck portion 36 which extends between headportion 34 and outer circumferential surface 130. The diameter of neckportion 36 of linker pin 32 is narrower than head portion 34.

Necklace-side connector 28 of second swivel linker 26 has an openingpassing radially through it which forms cavity 21. Interior surface 23of cavity 21 is substantially rotationally symmetric with a contourwhich is complementary to the outside surfaces of linker pin 32. Inparticular, interior surface 23 of cavity 21 has an outer portion 143which corresponds to neck portion 36 of linker pin 32 and includes anexpanded radially inner portion, i.e., groove 31, which corresponds tohead portion 34. Outer portion 143 has a smaller inside diameter thangroove 31.

Linker pin 32 of holder-ring-side connector ring 30 of second swivellinker 26 may extend within cavity 21 of the necklace-side connector 28of the swivel linker 26 and is retained against withdrawal in the swivelaxis direction by interference between the greater outside diameter ofhead portion 34 of linker pin 32 and the smaller inside diameter ofouter portion 143. The inside diameter of groove 31 is sufficientlygreater than outside diameters of corresponding portions (e.g., headportion 34) of the linker pin 32 to provide clearance for linker pin 32to rotate unimpeded about swivel axis 140 in groove 31 and cavity 21.

As shown best in FIGS. 2-3, eyeglass-holder ring 22 passes through aconnector-ring central opening 40 in holder-ring-side connector ring 30of second swivel linker 26 to connect swivel linker 26 toeyeglass-holder ring 22. Second necklace end 18 is thus connected to theeyeglass-holder ring 22 by second swivel linker 26. Corresponding tosecond swivel linker 26, eyeglass-holder ring 22 has a second pair ofswivel-linker collar stops 42 and 44 extending around theeyeglass-holder ring 22 on opposing sides of the holder-ring-sideconnector ring 30 of the second swivel linker 26, as may be seen in FIG.4. The second pair of swivel-linker collar stops 42 and 44 fixes theposition of the second swivel linker 26 azimuthally on theeyeglass-holder ring 22. A distance between facing surfaces ofswivel-linker collar stops 42 and 44 of the second pair is greater thana thickness of holder-ring-side connector ring 30 between the collarstops by a pivot-motion clearance amount. Similarly, an inside diameterof central connector-ring opening 40 in holder-ring-side connector ring30 is greater than the outside diameter of the portion ofeyeglass-holder ring 22 passing through the central opening 40 by apivot-motion clearance amount. Clearance is therefore provided forsecond swivel linker 26 and eyeglass-holder ring 22 to pivot freelyrelative to one another.

A second pivot axis may be defined for the pivotal connection betweenthe eyeglass-holder ring 22 and the second swivel linker 26 as a secondpivot axis 150 about which pivotal motion between eyeglass-holder ring22 and swivel linker 26 can occur as best shown in FIG. 4. Second pivotaxis 150 extends approximately in the plane defined by theeyeglass-holder ring 22. Swivel axis 140 of second swivel linker 26extends substantially perpendicular to second pivot axis 150.

First swivel linker 24 includes a holder-ring-side connector ring 70rotatably connected to a necklace-side connector 50 by thepin-and-socket arrangement described above in connection with the secondswivel linker 26, as depicted in FIGS. 5-6. Necklace-side connector 50includes an interior surface 53, an interior 51, a top end 57, a lowerend 59 and a groove 56, similar to necklace-side connector 28.Eyeglass-holder ring 22 passes through a central opening 192 in theholder-ring-side connector ring 70. As best depicted in FIG. 6, a firstpair of swivel-linker collar stops 72, 74 extend around theeyeglass-holder ring 22 on opposing sides of holder-ring-side connectorring 70 of first swivel linker 24 to fix the position of first swivellinker 24 azimuthally on eyeglass holder ring 22. Clearances areprovided between the swivel-linker collar stops 72, 74 andholder-ring-side connector ring 70 of first swivel linker 24 and betweeninside surfaces of central opening 192 in holder-ring-side connectorring 70 and outer surfaces of the portion of eyeglass-holder ring 22passing through central opening 192 to permit eyeglass-holder ring 22and first swivel linker 24 to pivot freely relative to one another. Thepivoting of first swivel linker 24 and eyeglass-holder ring 22 relativeto one another occurs about a pivot axis 180 which extends approximatelyin the plane of eyeglass-holder ring 22 and generally perpendicular to aswivel axis 190 of first swivel linker 24. Swivel axis 190 may besubstantially aligned with a longitudinal axis of first end 16 ofnecklace 14 and/or a longitudinal axis of necklace-side connector 50.

Turning again to FIG. 1, the first pair of swivel linker collar stops72, 74 and the second pair of swivel-linker collar stops 42, 44respectively fix the positions of first swivel-linker and second swivellinker 26 azimuthally at a separation from one another of about 90degrees of arc about eyeglass-holder ring 22.

A central opening 76 of the eyeglass-holder ring 22 of theeyeglass-holder assembly 20 defines a temple-piece-receiver ring opening76. Eyeglasses 12 in a folded closed configuration can be held in theeyeglass-holder ring 22 with temple piece 78 of the eyeglasses extendingdownwardly from one side of the temple-piece-receiver ring opening 76and the lens frame 80 of the eyeglasses extending downwardly from theopposite side of ring opening 76. The first and the second swivellinkers 24 and 26 relieve twisting which can occur in necklace 14 as aresult of movement of the wearer of necklace assembly 10, so thatnecklace 14 and eyeglass-holder assembly 20 bearing the eyeglasses 12tend to lie neatly on the chest of the wearer.

It is not intended to limit the present invention to the specificembodiments described above. For example, the eyeglass-holder loop ofthe eyeglass-holder assembly of the necklace assembly of the inventioncould have an oval, hexagonal, octagonal, serpentine or othernon-circular shape. Jewelry chains or strings of beads of a wide varietyof styles may be used for the necklace of the necklace assembly of theinvention.

Further, the necklace-side connectors and holder-ring-side connectorrings may be formed of various shapes and sizes configured to connect tonecklaces and eyeglass-holder loops, respectively. For example, thenecklace-side connectors could be spherically shaped. Also, a cavity(e.g. cavity 21) of a necklace-side connector (e.g., necklace-sideconnector 28) could be of any of various shapes and sizes configured toreceive various size projecting components (e.g., pin 32) of variousshaped holder-side connectors (e.g., holder-ring-side connector ring30). Also, grooves (e.g., groove 32) in such cavities of suchnecklace-side connectors could be of various shapes and sizes configured(e.g., shaped and dimensioned) to receive such projecting componentswhile rotatably connecting the necklace-side connectors and projectingcomponents. Also, loop portions (e.g., loop portion 132) of holder-sideconnectors (e.g., holder-ring-side connector rings 30) may be continuousloops without openings when connected to necklace-side connectors (e.g.,necklace-side connector 28). Alternatively, one or more loop portionsconnected to an eyeglass-holder loop (e.g., eyeglass-holder loop 22) maybe openable at one or more locations to allow releasable attachment ofsuch loop portions to the eyeglass-holder loop.
